16 POINTS HELP ASAP plzzzzzzzzz
schepotkina [342]

Answer:

                            \large\boxed{\large\boxed{\sqrt{3}

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare \sqrt{3} \text{ }and\text{ } 2\sqrt{3} because they have the same radicand.

You can order: \sqrt{3}

You can introduce the 2 inside the radical by squaring it:

       2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}

Since 5 is between 3 and 12, you can order:

  • \sqrt{3}

Which is:

  • \sqrt{3}

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, \sqrt{5} and \sqrt{5}

Now you must determine whether π is less than or greater than \sqrt{12}

Using a calculator or probing numbers between 3 and 4 you get \sqrt{12} \approx3.46

Hence, the complete order is:

  •            \sqrt{3}
